DUPLEX FLASHING-BLOCK.

To all'whom it may concern:

Be it' known that I, FELIX D. RENAUD, a citizen of the United States, and aresident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Duplex Flashing-Block, of which the following is a full, clear, and exact description.

This invention relates to a flashing construction and has for an object the provision of an improved arrangement which may be used with a vertical wall, chimney, skylight inclosure and the like without injuring these. members, while providing a proper connection between the various members.

Another object in view is to provide a strong, durable and efiicient weather proof connection between the roof and the build ing walls at a minimum cost in installing.

A still further object of the invention is to provide a flashing in which the flashing members are arranged so that a part thereof will be above the surface of the roof.

In the accompanying drawing:

Figure 1 is a fragmentary sectional view taken through a vertical wall of a building and the roof thereof showing the roof struc ture connected to the wall by a flashing structure formed according to the present invention.

Fig. 2 is a perspective view of the flashing block and the shield or key associated there with.

Fig. 3 is a view similar to Fig. 1 showing the parts enlarged for better illustrating the construction.

Referring to the accompanying drawing by numerals, 1 indicates the wall of.a building provided with a fire wall or parapet 2 to which the flashing structure 3 as a whole is connected. The wall 1 supports the various joist 4 on which the roofing boards 5 are positioned, said boards in turn supporting the felt 6. Felt 6 extends to the flashing block 7 as shownin Fig. 3, and preferably is of such a length as to extend upwardly along the wall 8 thereof for a short distance. A counter flashing strip 9 is provided so that the lowermost layer thereof extends upwardly along the vertical bearing surface 10 across the horizontal bearing surface or shoulder 11 and from thence downwardly over the felt 6 any desired distance. Suitable nails or tacks 12 are provided for holding the felt 6 in position and other tacks Specification of Letters Patent.

or nails 13 are used for holding the counter flashing 9 in position, said tacks 13 being preferably arranged beneath the shield or key 14. The remaining layers of the strip 9 aside from the bottom layer extends only to the bearing surface 10 whereby the end 15 of the shield14 may extend into the notch or groove 16 and press against the single vertical layer and rest against all of the layers of the counter flashing 9. If desired cement or other material may be used for fillin in any space not occupied by the counter ashin and the end 15 whereby the shield 14 will be held in position and also all of the parts will be tightly connected together. The shield 14 is provided with an inclined surface 17 which extends to the vertical outside wall 18. Preferably the inner lower part of the shield 14 is cut away at 19 so as to allow for a slight movement of the flashing during expansion, thus providing for the natural condition of the material and the action of the elements thereon without causing the shield 14 to become loose, or any of the parts to be displaced. It will be noted that the horizontal bearing surface or shoulder 11 is spaced an appreciable distance above the top of the roof so that even if the parts, move somewhat under contraction or expansion there will be no leaking and if the snow banks up an appreciable distance the arrangement is such that the water cannot readily back up and leak through on to the boards 5.

After the parts have been arranged as described the top coating of composition and gravel 20 is applied whereupon the roof is completed and the flashing properly positioned. It will be noted that the flashing groove or recess spaced above the bottom of .the block, a flashing strip extending across the bottom of said groove downwardly along the wall of the block below the groove and then in a direction substantially parallel with the bottom of the block and a shield with one leg positioned in said groove, and the other leg resting on the lower horizontal part of the flashing strip.

2. A roof construction embracing in combination with a roof connecting roof strips, a vertical wall or member formed near the roof level with a recess to receive the flashing ends of said strips, said strips having a section extending horizontally in said recess and then vertically against the back wall thereof, and a flashing block fitting in said recess between the top of the recess and said flashing strips, said block holding the vertical section of said-flashing strip in position.

a 3. A roof construction embracing in combination with a roof including roofing strips, a vertical wall or member formed adjacent the roof level with a recess, a flashing block fitted into said recess, said flashing block having a groove extending longitudinally thereof 7 substantially midway the height thereof, and acounter flashing strip engaging said first mentioned stripsextendinginto said groove, one of the layers of said counter flashing strip extending up the vertical Wall of said groove, and a shield having a vertical leg fitting against the counter flashing strip and a horizontal leg fitting into said recess and substantially fitting the same, said last mentioned leg being arranged in said recess above the counter flashing strip.

t. A flashing structure comprising a flash= ing block provided with a longitudinally arranged groove or, recess in one ,face, a notch in one corner and a lug on the opposite cor ner for fitting in a similar notch on the next block whereby the blocks may be alined when in use, said recess being spaced above the bottom of the block for receiving the flashing ends of roofing strips, and a shield 40 member formed substantially L-shaped in cross section, whereby one leg may fit into said recess and the opposite leg rest on said flashing strips.

5. A flashing structure.comprising a flash- 5 ing end or roofing strips, acounter-flashing strip connected with saidfla'shing ends and overlapping the same, a flashing block formed with a recess above said counterflashing strip, said recess having a substantially horizontal lower Wall and a substantially vertical back Wall, one of the strips of said counter-flashing strips extending along said bottom wall and forwardly along the vertical wall, while the remaining counter-flashing strip extends only over the vertical wall, and means fitting into said recess for holding the counter-flashing strips there in, said means overlapping part of the outer end of said counter-flashing strips.
